DiFX: A Software Correlator for Very Long Baseline Interferometry Using Multiprocessor Computing Environments [PDF]

open access: yes, 2007
We describe the development of an FX‐style correlator for very long baseline interferometry (VLBI), implemented in software and intended to run in multiprocessor computing environments, such as large clusters of commodity machines (Beowulf clusters) or ...

Quantitative Analysis Reveals Hitchhiking Drives Polysorbate Hydrolase Persistence Via Host Cell Protein–Antibody Interactions

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Polysorbate‐degrading host cell proteins (HCPs) represent a critical challenge in the manufacturing of monoclonal antibody therapeutics due to their potential to persist during downstream processing. While their enzymatic activity has been characterized, the role of direct HCP‐mAb interactions, particularly those involving polysorbate ...

Search for Compact Extragalactic Radio Sources Near Massive Star Forming Regions [PDF]

open access: yes, 2006
We have used the Very Large Array to search for compact milliarcsecond-size radio sources near methanol masers in high-mass star-forming regions. Such sources are required for Very Long Baseline Interferometry phase-referencing observations. We conducted

Study of the atmospheric pressure loading signal in very long baseline interferometry observations [PDF]

open access: yes, 2003
[1] Redistribution of air masses due to atmospheric circulation causes loading deformation of the Earth's crust, which can be as large as 20 mm for the vertical component and 3 mm for horizontal components.

Very Long Baseline Interferometry of Solar Flares [PDF]

open access: yesInternational Astronomical Union Colloquium, 1983
The aim of the VLBI experiment was a search for the occurrence of subarc- second microwave emission centres as tracers of the initial energy release in solar flares. The observations extended over the period April 28 to May 3, 1981 and were performed with the 25 m telescopes at Onsala (Sweden) and Dwingeloo (Netherlands) at a wavelength of 18 cm (1663 ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Can the supermassive objects at the centers of galaxies be traversable wormholes? The first test of strong gravity for mm/sub-mm very long baseline interferometry facilities [PDF]

open access: yes, 2013
The near future mm/sub-mm very long baseline interferometry experiments are ambitious projects aiming at imaging the “shadow” of the supermassive black hole candidate at the center of the Milky Way and of the ones in nearby galaxies.

Nanomaterials and Eco‐Friendly Refrigerants in Vapor Compression System: A Review of Performance and Sustainability

open access: yesEnergy Science &Engineering, EarlyView.
This review highlights how nano oils and eco‐friendly nano refrigerants enhance energy‐efficient refrigeration by improving thermal conductivity, lubrication, and system performance. The integration of rheological and tribological testing confirms reduced compressor work, better heat transfer, and higher COP using sustainable, low‐GWP refrigerants for ...

Aldebaran's angular diameter: how well do we know it? [PDF]

open access: yes, 2005
The bright, well-known K5 giant Aldebaran, alpha Tau, is probably the star with the largest number of direct angular diameter determinations, achieved over a long time by several authors using various techniques.
